23.4
The flash memory is controlled by means of the pins shown in table 23.2.
Table 23.2 Pin Configuration
23.5
The flash memory has the following registers. To access FLMCR1, FLMCR2, EBR1, or EBR2,
the FLSHE bit in the serial/timer control register (STCR) should be set to 1. For details on the
serial/timer control register, refer to section 3.2.3, Serial Timer Control Register (STCR).
23.5.1
FLMCR1, used together with FLMCR2, makes the flash memory transit to program mode,
program-verify mode, erase mode, or erase-verify mode. For details on register setting, refer to
section 23.8, Flash Memory Programming/Erasing.
FLMCR1 is initialized to H'80 by a reset, or in hardware standby mode, software standby mode,
sub-active mode, sub-sleep mode, or watch mode.
